OK all is working well... a slightly unrelated question; is Microsoft.SPOT.Hardware.UsbClient supported by the Netduino+ 4.2 firmware (or standard Netduino)? I'm getting an UnsupportedException from the UsbController constructor so I'm guessing not?

The first time you run the app, press the button to change the transport. Then once it reboots, erase the current app (using the new transport port) and you'll be good to go.

Fantastic, works like a charm. I've tried with COM1 and COM2 and both work fine so the reset IRQ doesn't appear to be a problem. The only thing I did notice is that MFDeploy doesn't work via serial (Ping/Erase) but VS can deploy and debug fine.

Thanks for your help Chris.

Can you try using COM2 for debug really quickly, instead of COM1?

Just tried with COM2, exactly the same (reset on boot).

Does that get you connected alright?

Well it helps if the test program doesn't use the COM :-) I've managed to get a response in MFDeploy via serial but it just seems to be resetting constantly. This is the serial output:

Then reset. The code is just:

Transport.SetInterface(TransportInterface.Com1);
Thread.Sleep(Timeout.Infinite);

Can you try adding SecretLabs.NETMF.Diagnostics.dll as a reference to your project? And then running the following line of code (deployed via WinUSB)?

SecretLabs.NETMF.Diagnostics.Transport.SetInterface(TransportInterface.Com1);

Done this, the N+ now has the ethernet lights and the blue LED flashing every 5 seconds and the USB device isn't recognised. I'm using a 3.3V TTL <-> Usb cable plugged into D3/4 (and ground), tried swapping the two around in case I had RX/TX the wrong way around but am unable to ping with MfDeploy either way.
